Description

Little background: I have a script that reads emails and puts them in a sqlite database. It's actually a lot of code. I've been running it successfully with ruby 1.8.7 and jruby 1.6 for a while, I'm trying out jruby 1.7 now to test for a ruby 1.9 conversion.

Here's the stack trace I get. My test case currently consists of everything so I'd rather not post that, but I'd like to provide any other info or testing that's helpful.

It consistently crashes on processing the fourth email, regardless of the contents of any of them. I guess that's indicative of some jit or other optimization warming up?

Just to confirm, if I use -Xcompile.invokedynamic=false, I make a lot more progress before stopping with an unrelated (likely mine) error.

Is /home/tedu/proj/sailer/sqlite-ffi.rb:88 something I could see? It would help to know what actual Java method it's calling at that point (it is a Java method call).

I could not reproduce with a trivial example. Need to know better what's happening at that line of code...

system ~/projects/jruby $ jruby -rjava -e "Java::Blah.blah(true, true, true, true, true)"

system ~/projects/jruby $ jruby -rjava -e "5.times {Java::Blah.blah(true, true, true, true, true)}"

system ~/projects/jruby $ cat Blah.java
public class Blah {
  public static boolean blah(boolean a, boolean b, boolean c, boolean d, boolean e) {
    return true;
  }
}

sure, the entire source for that is at https://github.com/tedu/sqlite-ffi/blob/master/sqlite-ffi.rb

line 88 is SqliteFFI.bind_blob st, argpos, arg, arg.length, -1
bind_blob is attach_function :bind_blob, :sqlite3_bind_blob, [:pointer, :int, :pointer, :int, :size_t ], :int

five arguments, but none boolean.

I have a little time now to try making a smaller test with just that file.

here's a test case, using the sqlite-ffi binding.

require "sqlite-ffi"

dbh = SqliteFFI::Database.new "test.db"
dbh.execute "create table sss (s text)"
dbh.execute "create table bbb (b blob)"

100.times do |i|
p i
dbh.execute "insert into sss (s) values ", "hello"
dbh.execute "insert into bbb (b) values ", "data\0\0stuff"
end

That consistently prints numbers up to 24, then crashes with a similar stack trace.

Proactively calling this fixed by the fix for #185 (https://github.com/jruby/jruby/issues/185).

Ted: It turns out there are multiple reports that all have the same backtrace, and #185 should fix it. If you can, please test JRuby head and confirm.
